Abstract

The interpretation of a measured
x-ray
spectrum from a carbon
plasma induced by subpicosecond laser pulses [Wilhein, T., et al., J. Opt. Soc. Am. B15, 1235 (1998)] is reexamined. We calculate a synthetic Lyman spectrum emitted from a plasma layer at a given temperature and density, using a microscopic approach to the line shape in dense, non-ideal plasmas. Self-absorption is taken into account within a simple model considering one-dimensional radiation transport in a plasma layer. We infer a temperature of
and an electron density of
